Clearwing 2

As mentioned before, there are still remnants of the Clearwing mutation (or Pastel as it has been called) in Australia. They are a recessive trait and traditionally they occur in Ginger and Dilute Ginger Bengalese Finches.

As seen above the Mutation can vary into other colours

 

Especially here we see a fairly dark Red/Brown (Ginger) and personally think it has quite a striking appearance with the heavier contrast

I am curious as to whether the Clearwing Mutation can occur in the darker birds like the Chestnut and Chocolate. I will be keeping an eye out for any images to share.
